Research Abstract

The electric-field-induced optical second-harmonic generation (EFISHG) measurement, which can directly probe carrier behavior in organic multilayer light-emitting diodes (OLEDs), was studied. The EFISHG measurement system is capable of catching carrier processes in the time range from 10 ns to 25 ms with carrier density > 10-7 C/cm2.
